Resetting Pro Tools I/O

Pro Tools' I/O settings can get changed for a number of reasons and it is sometimes necessary to reset the Pro Tools I/O to resolve issues with routing audio in to and out of Pro Tools. Follow the process below to reset your Pro Tools I/O.

You will first need to make sure that the Apollo is selected as your Playback Engine within Pro Tools. To do this, open Pro Tools and navigate to Setup > Playback Engine and make sure 'Universal Audio Apollo' is selected.

Next, navigate to Setup > I/O and click on the 'Input' tab when the I/O Settings window appears.

On the 'Input' tab, select all paths shown and click 'Delete Path'. Delete all paths on this tab so it is completely empty.

Once all paths are deleted, click the 'Default' button. This will re-populate the tab with the correct paths.

Repeat these steps for the 'Output', 'Bus' and 'Insert' tabs as well.

Note for Apollo Thunderbolt users on Mac OS X: The Apollo I/O can be manually changed on the Core Audio tab of the Console settings. If any changes are made to the Apollo I/O via the Core Audio tab the Pro Tools I/O will need to be reset to reflect these changes.
